Marantz Split Knob Inner Knob for 22xx and 23xx Series

Product Description

Enhance your vintage Marantz restoration with our premium inner knob for split knob tone controls, proudly designed and manufactured in the USA. This listing is for the inner knob only, part of the split knob assembly used to independently adjust left and right channel tone settings (e.g., bass, treble) on Marantz 22xx and 23xx series receivers with split tone control knobs. Crafted from high-quality aluminum with a durable clearcoat finish, this inner knob complements the outer knob for a seamless, authentic Marantz aesthetic. Available in a Gen1/2 combined variation (no face distinction) to match your receiver’s era, with a Gen3 knurled variation coming soon. Pair with our outer knob (sold separately) or check our upcoming split knob set to complete your tone control assembly. Combine with our Marantz faceplates for a restoration that looks better than new.

Important Compatibility Note: This inner knob is designed for the split knob tone controls of Marantz 22xx and 23xx series receivers with split tone control knobs (e.g., 2240, 2250, 2270, 2325). It is not compatible with models using single knob designs or other series. Verify your receiver’s tone control style before ordering.

Mounting Details: The inner knob mounts securely using a D-shaft, ensuring a precise fit and easy installation.

Marantz Split Knob Inner Knob Identification Guide (22xx and 23xx Series)
